Abstract (en)
[origin: EP0806396A1] Preparation of (mixed) tin (Sn) disulphides of formula (SnxMe1-x)S2 (I) comprises reacting a mixture of the metals Sn, Me and/or Me sulphide and a stoichiometric excess of sulphur (S), in which the amount of S is NOTLESS 3 mole with respect to x. Me = titanium (Ti), molybdenum (Mo), iron (Fe), chromium (Cr), tantalum (Ta), niobium (Nb), manganese (Mn), bismuth (Bi), tungsten (W) and copper (Cu); x = 0.5-1. Reaction is carried out in an inert atmosphere in the presence of halide decomposing without residue under the reaction conditions and/or Sn and/or Me halides in an exothermic reaction. Also claimed is a method of converting (I) to dimetal trisulphides (II).
